OpenCL at SC14

SC14During SC14 (SuperComputing Conference 2014), OpenCL is again all over New Orleans. Just like last year, I’ve composed an overview based on info from the Khronos website and the SC2014 website.

Finally I’m attending SC14 myself, and will give two talks for you. Tuesday I’ll be part of a 90 minute session of Khronos, where I’ll talk a bit about GROMACS and selecting the right accelerator for your software. Wednesday I’ll be sharing our experiences from our port of GROMACS to OpenCL. If you meet me, then I can hand you over a leaflet with the decision chart to help select the best device for the job.

There are other interesting SC14-events around OpenCL, so be sure to check the schedule carefully – especially the posters!


Below links bring you to special SC14 landing-pages.

  • Altera -FPGAs
    • Booth #3821. Altera will demo of rapid prototyping using OpenCL, and a demo of optical flow on an embedded SoC.
    • Booth #3921: Bittware will demo the available tools necessary to begin developing applications for the Altera Stratix V using OpenCL.
    • Booth #1332: Nallatech has lots and lots of OpenCL. Ask for demo’s and read the big poster.
  • AMD – FirePro GPUs.
    • booth #839: Demo of Gromacs. Ping me for a personal demo.
    • Small theatre at booth #839 will have several OpenCL-related talks (see also agenda above).
  • ARM – low-power HPC
    • Booth 3458: Not sure, if they have OpenCL demo’s, but good chance there are.
  • Intel – CPUs, Accelerators
    • Booth #1215, #1315. Most times don’t demo OpenCL at HPC events, but they can tell about it.
  • NVIDIA -Tesla GPUs
    • Booth 1727: will not present OpenCL, but every time they’re funny when asked what they do about OpenCL. So go visit them and ask about i.e. OpenCL 2.0.
  • Texas Instruments – DSP
    • Booth 3745: Not sure if they’ll demo their OpenCL solution, but hope so. Will update, once I know.
  • Xilinx – FPGAs
    • Booth 3903, 4003. Will present “the industry leading OpenCL solution”. Be sure to check out and compare with Altera’s solution.
  • Kalray – multi-core processor
    • Booth 2815. Will demo a new processor and have OpenCL-demo’s (alpha product).
  • ArrayFire – HPC library
    • Booth #2725. will demo their library with backends for both OpenCL and CUDA.
  • Mont-Blanc – ARM-based HPC
    • Booth #1039. Will show literally cool supercomputers.

The floorplan with accents on the Khronos members can be found at Khronos’s site, as PDF.

At SC14 and saw great OpenCL demos or news?

    Do you have links to videos of any these talks and/or your own presentation?

    I overheard many conversations at SC ’14 about the dislike for CUDA and the preference of OpenCL. Not only has NVidia not supported OpenCL since 2010, it only supports version 1.1 with C bindings. Doesn’t support 2.0, C++, or SPIR, all of which contain important enhancements. Clearly a strong-arm tactic. You can purchase a, AMD FirePro GPU, equivalent to an NVidia Kepler, for 1/3 the price!

      Heard the same things, but thought it was because most people know me for supporting OpenCL. Nice to hear, you heard it too!

      The success of OpenCL on AMD FirePro is crucial for OpenCL in general. Then we make sure the competition is on OpenCL-capable hardware, not between CUDA and OpenCL. I’m therefore very happy FirePro won the Green500! If AMD succeeds in getting a few more clusters in the Top500 or Green500, then we’re there!
